31 % The final reference card has six columns, three on each side.
32 % This file can be used to produce it in any of three ways:
33 % 1 column per page
34 % produces six separate pages, each of which needs to be reduced to 80%.
35 % This gives the best resolution.
36 % 2 columns per page
37 % produces three already-reduced pages.
38 % You will still need to cut and paste.
39 % 3 columns per page
40 % produces two pages which must be printed sideways to make a
41 % ready-to-use 8.5 x 11 inch reference card.
42 % For this you need a dvi device driver that can print sideways.
43 % Which mode to use is controlled by setting \columnsperpage above.

638 The argument to \kbd{interactive} is a string specifying how to get
639 the arguments when the function is called interactively.
